The best resources I found out about are through the Society for Accessible Travel and Hospitality website. This is a nonprofit organization and it includes many other helpful sites, travel tips, and partners.
Another site to search is wheelchair traveling which includes resources on travel agents, accommodations and land travel for people with disabilities.
Lastly check with your nearest medical care facility serving spinal cord injured people. The social workers there should also be able to help with suggestions and referrals.
